The Fall of Witches - Brandon H. C. Lim

Nyree and Elias Forester are back in the thick of it. Bullies at school. Open hostilities between the two Faery Courts. Witches in the woods. The looming threat of the Coranaid, an ancient enemy who can hear any words spoken anywhere in the world. With all this a closely held secret from family and friends, Nyree and Elias have few allies to fall back on.

The arrival of refugee gryphons from the middle-east provides the final spark for war among the Faeries. But what drove the gryphons from their home? Could it be related to the Forester's own enemy?
